Able’s basic earnings per share (EPS) ((Net Income ? Preferred Stock Dividends) / weighted average shares outstanding) for 2004 was (($720,000 ? ($500 × 6,000 × 0.03) ? ($1,000 × 1,000 × 0.08)) / 1,000,000 =) $0.55. If the convertible preferred were converted to common stock on January 1, (6,000 × 40 =) 240,000 additional shares would have been issued. Also, dividends on the convertible preferred would not have been paid.
So we have diluted EPS was ($720,000 ? 80,000) / (1,000,000 + 240,000) = $0.52.
